Java 大数类

划分结果存在数组。供应商下标0 在剩下的标记1

import java.math.BigInteger;
import java.util.Scanner; 

public class Main {
	public static void main(String args[]){
		Scanner in = new Scanner(System.in);
		BigInteger a = in.nextBigInteger();
		BigInteger b = in.nextBigInteger();
		System.out.println("Add " + a.add(b));
		System.out.println("Sub " + a.subtract(b));
		System.out.println("Multi " + a.multiply(b));
		System.out.println("Div " + a.divide(b));
		System.out.println("Max " + a.max(b));
		System.out.println("Min " + a.min(b));
		BigInteger result[] = a.divideAndRemainder(b);
		System.out.println("Divide " + result[0] + " Remainder " + result[1]);
	}
}
